Test Step 1. Verify Activation of the Idle Shutdown Timer
Connect Cat ET to the data link connector.
Access the customer parameters.
Access the following display screens in order:
"Service"
"Configuration"
Record the programmed time for the "Idle Shutdown Time". The "Idle Shutdown Time" must be between 3 and 1440 minutes. If the "Idle Shutdown Time" is programmed to zero, then the timer is disabled.
Record the current value of the parameter "Allow Idle Shutdown Override" and the parameter "Idle RPM Limit".
Start the engine. Allow the engine to warm up until the coolant temperature is 38 °C (100 °F). Allow the engine to operate at the programmed low idle.
Ensure that all unnecessary loads are turned OFF.
Park the vehicle.
Ensure that "Vehicle Speed" on the Cat ET status screen is 0 km/h (0 mph).
Ensure that "Engine Speed" on the Cat ET status screen is at "Low Idle".
Ensure that the clutch pedal and the brake pedal are not depressed.
Ensure that the status of the "PTO On/Off Switch" is OFF.
Observe the "Idle Shutdown Status". Expected Result:Result 1 The "Idle Shutdown Status" indicates "Counting".Result 2 The "Idle Shutdown Status" indicates "Not Active".Results:
Result 1 - The ECM is reading the proper conditions for the activation of the "Idle Shutdown Timer". Proceed to Test Step 2.
Result 2 - The ECM is not reading the proper conditions for activation of the "Idle Shutdown Timer". Proceed to Test Step 3.Test Step 2. Verify the Driver Alert Function for Idle Shutdown and the Override Function for Idle Shutdown.
Verify that Cat ET is connected to the data link connector.
Access the customer parameters on Cat ET.
Access the following display screens in order:
"Service"
"Configuration"
Record the programmed time for the "Idle Shutdown Time". The "Idle Shutdown Time" must be between 3 and 1440 minutes. If the "Idle Shutdown Time" is programmed to zero, the timer is disabled.
Reprogram the "Idle Shutdown Time" to three minutes for this test.
Observe the following items during the 90 second period before the programmed shutdown time:
Check engine lamp
"Idle Shutdown Status"
If the customer parameter of "Allow Idle Shutdown Override" is programmed to "YES", perform either of the following actions in order to override the shutdown:
Press the clutch pedal.
Press the service brake pedal.Note: The pedals must be pressed while the check engine lamp is flashing. The check engine lamp flashes during the 90 second period before the programmed shutdown time.
Reprogram the "Idle Shutdown Time" to the value that was recorded earlier for this test. Expected Result:During the 90 second period before the scheduled shutdown, the status should change from "Counting" to "Driver Alert" and the check engine lamp should flash rapidly. If the "Allow Idle Shutdown Override" is programmed to "YES", the "Idle Shutdown Status" should change to "Override" after the pedals are depressed.Result 1 The idle shutdown timer behaves in the manner that is described above.Result 2 The check engine lamp did not flash during the alert.Result 3 The ECM did not sense a change in the status of the service brake.Result 4 The ECM did not sense a change in the status of the clutch.Results:
Result 1 - The idle shutdown timer is operating properly.STOP
Result 2 - The check engine lamp did not flash during the alert.Repair: Perform the following diagnostic procedure: Troubleshooting, "Check Engine Lamp Circuit - Test"STOP
Result 3 - The ECM did not sense a change in the status of the service brake.Repair: Perform the following diagnostic procedure: Troubleshooting, "Service Brake Pedal Position (Switch 1) Circuit - Test" STOP
Result 4 - The ECM did not sense a change in the status of the clutch.Repair: Perform the following diagnostic procedure: Troubleshooting, "Clutch Pedal Position Switch Circuit - Test"STOPTest Step 3. Check the State of the Related Conditions When the Vehicle is Parked.
Check the state of the following related conditions when the vehicle is parked:
Ensure that the vehicle speed is 0 km/h (0 mph) on Cat ET or the dash display.
Ensure that the engine is not in cold mode. (The Cat ET status screen will indicate that "Cold Mode" is "Active" in the corner of the display screen.)
Ensure that the PTO on/off switch is OFF.
Ensure that the engine is at low idle.Expected Result:Result 1 Vehicle speed is not indicated as 0 km/h (0 mph).Result 2 The Cat ET status screen indicates that the engine is in cold mode.Result 3 The status of the PTO on/off switch is not "OFF".Result 4 The engine is not at low idle.Results:
Result 1 - Vehicle speed is not indicated as 0 km/h (0 mph).Repair: Perform the following diagnostic procedure: Troubleshooting, "Vehicle Speed and Speedometer Circuit - Test"STOP
Result 2 - The status screen on Cat ET indicates that the engine is in cold mode.Repair: The engine must not be in "Cold Mode" operation while this test procedure is being performed. Allow the engine to run until the coolant temperature exceeds 20 °C (68 °F). Troubleshoot and repair any related conditions.STOP
Result 3 - The status of the PTO on/off switch is not "OFF".Repair: Perform the following diagnostic procedure: Troubleshooting, "PTO Switch Circuit - Test"STOP
Result 4 - The engine is not at low idle.Repair: Return the engine to Low Idle. Perform the test procedure again.STOP
